Milwaukee police said 28-year-old Daniel J. Kleinmann had met another man in the area of 17th and Layton streets just before 4 p.m. to sell him car parts.

According to the victim, Kleinmann was armed with a handgun and robbed the man who came to meet him, then drove away, crashing his car at 3rd Street and Tripoli.

Police said Officer Shawn Pecoraro, who was in full uniform and in a marked squad car, tracked the man down and tried to interview him. Police said that "during the encounter, the officer had reason to believe his life was in danger and he discharged his weapon, striking the suspect."

Police said Kleinmann was on probation and had been wanted on charges of felony escape and a probation violation.

A gun has not been recovered.

Police said Pecoraro, who is a 15-year veteran of the police department, has been placed on administrative duty while the police department and Milwaukee County district attorney review the case. He is 39 years old.
